Title: Prepayment coin-box telephone installation
IPC: H04M17/02
Filed: 1945-11-26
Abstract: 604,547. Automatic exchange systems. WOSER, O. Nov. 26, 1945, No. 31910. [Class 40 (iv)] In a prepayment coin box telephone installation the user first dials the number and the impulses are stored, indicating means are then operated to show the charge and when the charge is inserted the stored impulses are reproduced to actuate the exchange mechanism. In both embodiments shown, the call box apparatus MSt is connected with a switching system Ue which can connect the instrument with the impulse storing and charge indicating apparatus, and lastly connects the instrument to usual automatic exchange apparatus Ze and thus to the called person T. On a call being initiated, a line-finder as1 connects a charge indicating apparatus to MSt and relay A energizes over the line. Dialled impulses are repeated by A to magnet Sp to step wipers sp. When dialling ceases, the sluggish release of V permits one of the relays I, II-V to start the appropriate part of a talking machine Spr which announces the charge. The money is then placed in the coin box, causing the emission of impulses which step wiper mw, since differential relay X (only one winding shown) is operative. When wiper mw coincides with spIII, relay P starts the impulse reproduction apparatus. This consists of relays Y and Z which interrupt each other and send out impulses over t4 to the exchange equipment and also step wiper ag1. When sp1 and ag1 coincide, relay H followed by T operate and MSt is connected straight to Ze and the charge mechanism is disconnected. The arrangement shown in Fig. 2 gives a visible indication of the charge. The number is dialled and the impulses stored as in the first construction. Release of V then causes relay An to start up the impulse emitters Y and Z which step an indicator TM in the call box and also wiper tmw. When the latter operates relay K, the stepping ceases and the money should be inserted. The remaining operations are the same as in the previous construction. Means may be provided to give warning signals at the end of fixed intervals of conversation. In the case of the visual indicator the charge is shown throughout the call. In the alternative construction, the charge mechanism must remain seized throughout a call in order that the talking machine may repeat the charge. The machine may also include records that issue instructions as to the time to dial and to insert money.

Patent GB-392952-A (GB)
Title: Improvements in or relating to the manufacture of moulded products
IPC: B32B27/00
Filed: 1931-11-20
Abstract: 392,952. Vehicle bodies. ROGGEN, M. VAN, 2 bis. Rue Crespel, Brussels. Nov. 20, 1931, No. 32245. Convention date, Nov. 21, 1930. [Class 108 (i).] A process for making articles such as vehicle bodies and perambulators from paper, cardboard, paper pulp or wood-pulp, comprises impregnating the paper &c. sheets with a binding-agent, e.g. artificial resin, which is capable of being hardened by polymerization and pressing to shape, the binding agent being maintained in the liquid state until after the shaping operation and subsequently baked until it is completely hardened. One suitable form of apparatus consists of a model 3, which is a good conductor of heat, into which the sheets of material 2 are placed and made to assume as nearly as possible the shape of the mould. Flange-members 3b fixed to the top of the mould 3 by bolts 4 with interposed packing 12, extend beyond the thickness of the sheets and confine the edges thereof. Insulating sheets 5 are then placed over the sheets 2 and the mould filled with loose material 6 such as sand or granulated metal or shot. A plate 7 fitting exactly between the flanges 3b is placed on the material 6 and the apparatus is then placed in a press, the material 6 causing the pressure to be distributed uniformly over the surface of the sheets. For maintaining the plate 7 against the material 6 after removal from the press, pivoted bolts 9 are provided on the mould 3 and secure a locking-bar 8 in position. Springs 11 on the bolts 9 allow of movement of the plate 7 according to variation in the volume of the material due to differing heat conditions when the apparatus is baked to cause hardening of the binding agent by polymerization. In an alternative form of apparatus, fluid pressure exerted through a diaphragm is employed to press the sheets 2 against the mould 3. Parts of vehicle bodies may be strengthened by increasing at these parts the thickness of material or by disposing thin wooden plates or metal reinforcements between the sheets of paper. According to the Specification as open to inspection under Sect. 91 hardening may be effected in an autoclave, in which case, before placing in the autoclave, the plate 7 and pressure substance 6 is removed and strips are bolted to the flanges 3b to secure the sheets 2 in the mould. This subject-matter does not appear in the Specification as accepted.

Abstract: 1305326 Making electrical connections AMP Inc 9 July 1971 [24 Aug 1970] 32247/71 Headings B3A and B3Q Electrical connectors 14, Fig. 4, are inserted in a flange 10 of a coil bobbin 4 and the ends of the winding are crimped into U-shaped ferrules formed on the connectors. The bobbin is placed on a fixture 22 and a piston and cylinder device 56 is actuated to drive a slide member of an inserting device 40 and a connecting rod 68 to the right, Fig. 1. The leading connectors of connector strips 15, 15<SP>1</SP> are cut off and advanced towards the bobbin, while the rod 68 actuates a toggle mechanism to drive the bobbin leftward, thereby inserting the connectors in the bobbin flange. During this portion of the work cycle, arms 24, 24<SP>1</SP> are pivoted outwardly as pins 170, 170<SP>1</SP> ride up convergent portions 160, 160<SP>1</SP> of latch arms 156, 156<SP>1</SP> and lodge in front of shoulders 162, 162<SP>1</SP>. Tap wires 34, 34<SP>1</SP> from the bobbin are placed in notches 26, 26<SP>1</SP> in the arms. The connecting rod 68 is then retracted and the bobbin support moves to the right, Fig. 1, but the shoulders 162, 162<SP>1</SP> prevent movement of the arms 24, 24<SP>1</SP> and their ends pivot inwardly as their pivot pin 25 moves with the bobbin. The arms place the tap wires above the connector ferrules, which rest on anvils 28, 28<SP>1</SP>, and a die plate 32 is driven downwardly to crimp the ferrules about the tap wires. Slight elongation of the ferrule takes place during crimping and this is accommodated by providing a gap (151) between a slide member (136) and a retainer plate (144) on a main slide (80), Fig. 10 (not shown), to allow for movement of the member (136). As the die plate 32 moves downwardly it engages ears 166, (166<SP>1</SP>) on the arms 156, 156<SP>1</SP> pivoting them outwardly until the shoulders 162, 162<SP>1</SP> clear the pins 170, 1701, and springs (155), (155<SP>1</SP>), Fig. 13 (not shown), then cause the arms 24, 24<SP>1</SP> to pivot outwardly, to the position shown in Fig. 4. As the die plate moves upwardly the parts return to their original positions and the coil bobbin is removed from the fixture. The connectors are then bent manually to lie spaced from the winding.
